Just got your theme, because looks good. But after installing it I'm missing basics. Would be very great if the theme supports customizing options as standard in C5 over design/theme/customize and not only 3 settings. This is useless for a business corporate identity. And nobody select C5 to get things done over hard coding CSS/LESS files.
You should check "Fundamental" theme how it works there and the nice options for google fonts. Your theme would be perfect, if you provide the same powerful options.
